Leonardo Jardim's side also reached the semi-final of the Champions League.

Lemar's arrival would likely see Arsene Wenger break through the £100million spending barrier for the first time.

The £92m spent last summer - on Granit Xhaka, Shkodran Mustafi and others - was a record.

Wenger has already spent a club record £52m on Alexandre Lacazette and brought in Saed Kolasinac on a free transfer as he plots a way for the Gunners to return to Champions League and title contention.

However, the futures of Alexis Sanchez, who is set to return to training this week, Lucas Perez and Kieran Gibbs still need to be resolved.
